FOAM SYSTEMS : FROM HIGH TO LOW BULKING

>>> Background
Although water has always been the main element used in fire-fighting, its optimisation called for new methods and equipment.
Adding foaming products that have been developed by the chemical industry makes water more effective and increases its cooling power two-fold.

>>> Bulking and emulsifiers
- Definition of bulking:
The ratio that exists between the volume of a solution (water + emulsifier) used to begin with and the actual amount of foam generated (water + emulsifier + air).

From 0 to 25, this type is suited to external uses where it must reach distances of over 10 metres. It generates a heavy, water-rich foam.

From 25 to 300, this type is suited to both internal and external uses for fighting oil slick fires, on retention tanks and in any situation where you are likely to have to face large sheets of flames.

From 300 to 600 and above, this product has primarily been designed for use with the appropriate equipment in enclosed spaces or cellars (the foam is propelled through ducts by mechanical or hydraulic blowers). This equipment may be fixed or mobile.
High bulking systems can be set up in the event of a fire, even when people have not all been evacuated from the premises. The foam generated is air-rich and thus allows those unexpectedly caught up in the event to breathe normally as they are being evacuated.

>>> Personal and environmental safety
- In general, the emulsifiers produced are of the low toxicity type and harmless to Man under normal usage conditions.

- Emulsifiers, foaming solutions, foams and solutions generated by sedimentation will not attack the environment and their biodegradable properties satisfy French and foreign standards.

>>> Eco protection knowhow
- Identifying requirements and investigating the most appropriate and versatile solution
- Drafting technical and assistance specifications
- Installing and monitoring systems
